On the other hand , swimming is not only sporting activities but also mean relaxing , entertaining and expand relations , social interaction . So swim is a necessity for all classes of people , especially young people and children . The development of swimming movement is reducing the proportion of children drown each year creates wholeness of the word "Blessed " in each family . Along with recreational swimming needs increasing , numerous pool construction project is done from the national projects like the water sports center , pool competitions national parks leisure pool to serve public kinds of family pool .

However, any project not really promote effective economic and social . Construction investment pool is a complex problem requiring investors to have full information about many areas before making a final decision . JSC Construction and installation of swimming pools months' loss to cooperate with professionals has extensive experience in the field of consultancy , design , construction , installation , technology transfer for the construction of swimming pools, water park work . For the construction investment pool to achieve the highest efficiency , avoid unnecessary waste , properly serve each specific audience . We are pleased to advise the necessary information for an investment project to build a pool.

 

I. Socialization pool construction

 

According to the policy of the Party and the Government should enhance the socialization of investment in the construction of sports facilities especially the swimming pool issues - attracted many types of strata . As we all know , our country has many lakes, rivers, interlaced system , frequent floods . Every year, hundreds of cases of drowning extremely pitiful . So the Party and government have advocated universal swimming in schools , ward ... is absolutely correct . But to implement this policy , it is a pressing problem of our society . As tens of thousands of such schools where they would be taken ? This headache Ministry of Education and Training , Sports Commission and the authorities for years .

To find a way to resolve this issue we focus with the Association of water sports , high performance sports Department met several times and agreed goals set out some suggestions calling for community participation in early for children from including the cooperation of the Bank. Expected pilot schemes call for investment in the big city before because there is much more potential ...

 

II . The type of pool - Some basic requirements when building pool

 

 1 . Develop pool for kindergarten

 

- The swimming lessons for children kindergarten is necessary issues and rewarding . We should create swimming pools, simply saying, let me be acquainted with the country . Through the water like a fun exercise sessions help children eat , sleep better practical to improve the health of children . Results of experimental kindergarten Lieu Giai, Ba Dinh , Hanoi has indicated this . Leveraging a deep 25cm rong100m2 yard , the teacher filled with water pump and each week the children were taking turns to splash 2 times for 30 minutes . After 1 month the rate of sick leave by 50% . This forced me to eat all meals reduced 70 % . In particular , the splash class students , the girls always have to add rice to the diet of the children .

- With typical features are play areas for children should ask about the shape and decoration to attract young attractive . One point to note is the pool kindergarten how the overall architecture suitable to adorn more for school children . With a pool of kindergarten , the minimum required area of 50m2 . Max also need to 100m2 ( approximately 10m - 12.5m , width about 8m - 10m ) , it is best to simplify .

There are stairs up to the kid down easily

Working - floor brick slip groove or slot . Placement pool must be relatively airtight and have more sunlight . The depth of the pool should be between 0.4m - 0.6m is most reasonable . The use of this kind of gutter overflow in this pool is not necessary because the child was young foot fall prone to hurting children so should only use skimmer ( surface floating litter box cottage ) .

- Children are very sensitive subjects and vulnerable skin and especially the eyes of the child so the water quality is a top priority when designing filtration systems and water treatment . Typically filtering capacity for adult pool is 4 hours - 6 am , the entire country through the filter 1 type of pool is 2h/lan kindergarten .

- In the case where many children are divided into several cases to swim if conditions do not permit roofing can use sun screens stretched across two columns in two early morning last tank to the east while the west side is the shade from the sun for me .

- Construction cost pool ( see last section details ) .

 

2 . Develop pool for primary schools

 

- The school can and should organize swimming lessons for children of primary school age . But for students from class 3 , class 4 , class 5 grandchildren simpler class 1 , class 2 . If the children have felt the sinking buoyancy characteristics of water , only a teacher can teach a group of students from 15-20 children but not so hard . In elementary school children were relatively large , and often very crowded schools and students to share so many cases necessarily covered for summer sun 15h from 9am to swim when the sun will be vulnerable .

pool building schools Ngo Gia Tu

- Swimming pool at the elementary school , the depth from 0.8m - 1.2m is just right. The area from 150m2 - 300m2 tank ( length and width is 10m x 12.5mx 15m or 25m ) is guaranteed to learn to swim and swim . in large cities , often elementary school students all day , if the school has a swimming pool is a big advantage to attract students . At that , the organization had been done swimming lessons in a basically correct processes will have a positive effect on the health of students and wisdom .

pool players virtue elementary school

- At the age of students in grades 3 , 4 , 5 qualities of sport began to be evident . The school and swimming lessons will help schools and industries Sports training early detection and the talent they bring honor to the school and local .

swimming lessons for elementary school students

- The children of lower secondary students were aware of the dangers of depth as well as conscious obedience teacher . Because this time the children grew , the need to organize regular competitions take swim test by swimming pools popular ... so there should be sized in accordance with the provisions of the sports industry . - The most suitable tank size is 12.5mx 25m - 17,5 m x 25m or 25m x 50m ( if possible) with a depth of 1m - 1.4m .

 

3 . Develop pool for secondary schools

 

pool of high school in Japan

- For high school students have quite a height at this age to develop the qualities of health and athletic ability in children has been revealed clear . So can completely pool design , pool construction according to the specified size of the fitness industry thao.Tuy course , for convenient reference need some suggestions below.

 

 

III . The new technology in building pool

 

1 . The construction technology bottomless pool of U.S.

 

This technology people just build walls around about 1.2 m high . Haystack of golden sand poured down swinging around 1m depth obtained upon request from the outside design . Spraying water on the surface to cement in the construction process when stepping on the sand surface is not convex and concave . Then use PVC sheets Polyester Lining - Flag for the pool and the pool bottom . The biggest advantage of this type of technology is very fast construction time , low construction costs , usually applied to special areas of geological stability , the mainland territory has a high coefficient . The downside to shift underground tank bottom will be deformed or broken but the construction is extremely simple , cost negligible . When flooding if the water off the bottom of the tank will be shifted to peel pads to make the PVC bottom . This is consistent with the type of upland flooding and never require a good water treatment to remove restrictions to water , change the water . The cost of a pool of about 500m2 is used in this technology is about 400,000,000 - 450.000.000VND (including building tanks , water purification equipment , pool walls and floor coverings ) .

 

 

2.Cong Spei steel tank technology into Italy or Myrtha Pool

 

This technology uses a tank modular stainless steel or galvanized steel manufacturers are making available . Method of application of this technology is quite simple : after concreting requirements haystack broader range 700 - 1,200 mm ( depending on the area of ​​the tank to small ) were conducted on the modules assembled into pools by steel , complete installation of PVC sheets and bottom of the tank . With time the family pool construction concrete floor and assembled into pools of about 05 days , installing PVC Polyester Lining - Flag pool and water treatment equipment within 2 days . With such a large pool of 25m x 50m competition pool construction time and bottom of the tank for about 10 days , time sheets and fitted with an additional 8 days . Within 18-20 days can be put to use . Thus, this technology has the advantage of fast execution , high work life of 30 - 50 years . Another advantage is the ability to reuse the need to move the tank changes by placement cost is only removable modules into the old tank put in place reinforced concrete bottom pool ( concrete ) and replace it with a new buried pipe section . In Vietnam, this kind of technology applied tank assembly for water sports area - American DinhSEAGAME 2003 Ngoc Khanh public pools .

 

 

3 . Pools Technology into plastic panels , concrete Seamless Jean Desjoyau

 

This technology uses panels ( plastic ) as a permanent formwork tank then proceed monolithic pouring concrete for the pool walls and floor . Within 24 hours after installation can proceed PVC Polyester Lining - Flagpool completed . The advantage of this technology is very fast as construction technology into steel tanks . The downside is dependent , mandatory use of original equipment filter ( can not use the equipment of other vendors ) , cost 3 to 4 times higher filtration equipment of other vendors have equivalent power .

 

 

4 . The construction technology available pool assembled Spei - Italy

 

Apart from a small multi mount technology steel tank fitted a different technology popular in Europe due to the company Spei - Italian invention. This type of tank consists of prefabricated steel frame and PVC Polyester Lining - Flagpool in several standard sizes . This type of tank is very light weight structure itself is almost negligible . Assembly time is only 1-2 hours and can move very simple . This type of tank can be placed on the terrace , in the garden , the yard just have relatively flat ground without even concrete can be placed directly on the soil surface or ground natural grass . Good use of time from 5 to 10 years . This is the very best technology by Vietnamese tanks do not need to build , can be used immediately , easily move the location of the tank , can even fold up when not in use . The principal object using this type of tank is fitted for families , schools , resorts without any design or no decision will definitely put a fixed pool somewhere . It can meet the urgent needs to use the house as a foreigner rent they require pool . The hotels want to cater to the conditions but load -bearing structures on the roof is not enough to make a concrete tank .

 

 

IV . Concrete Pools - Issues to consider when building pool

 

1 . Bearing structure of reinforced concrete tank

 

Structural design problem pool is always controversial when building models of tank load . In recent years there have been many models preloading and different calculation methods used and results obtained are also very different . In the present system VN bearing structures of the kind of pool types , especially large competition pool occupies a relatively large proportion of economic construction cost estimates of this sort by the system fully reinforced foundations forced to use very expensive pile . Currently, in the world especially in European countries like France , Italy ... are using a computational model for structural concrete tank or quite meet the standard XD and technical safety factor of the tank and especially economic effect that it will make it simple structural tank construction , absolutely no need to use pressure pile . We are pleased to set out below an example of this calculation method for reference and apply :

For example :

- A ~ 2 tan/m2 2m deep pool - the water pressure to the bottom of 2.000kg / 10.000cm2 = 0.2 kg/cm2 .

- Concrete floor beams calculated dividing the average anti- tank screw 0,3 m

( 750 kg cm2 pressure = 0.075 kg/cm2 750/10.000 bottom .

- Total pressure on the land is : 0.2 + 0.075 = 0.275 kg/cm2 x 1.3 safety factor = 0.358 kg/cm2 .

So 0.358 kg/cm2 pressure was more than enough land safety without any public deposit .

In fact in VN , there were some pools that have been built have designed this tank model used successfully by structural calculations on pool Vo Exhibition , La Thanh hotel pool .. . A second point to note is that this tank will be constructed on soft ground ( land reclamation ponds ) in ground pressure of 0.36 kg/cm2 only two places that are not used to measure reinforcing the foundation piles . So far , after put into use almost 6 year when we examine the survey found the 2 pools on absolutely no difference subsidence incident occurred. According to the experience gained after the design and construction of pool 2 on , to completely eliminate the slightest incident can happen we usually wider bottom design of the tank from 0.5 - 1 0m to the safety and anti- bias settlement , award a bottom layer of sand 0.5 m elastic cushions . Anti subsidence pool , when we compute the design water line blocks with concrete cover thousands of tons equivalent so badly. In fact, that weight is spread out over the entire bottom surface should be almost negligible . If we apply this methodology we save billions of coins pile foundation . There are pools as in Dong Thap province alone was enough money pile foundation funding to build us a pool national standards . Besides the anti- anti- matter propulsion subsidence well to note also of interest because there is some work to remove water when cleaning tanks pushed emerged .

For example : Noi Bai Industrial Park in Hanoi tanks pushed 67cm of the ground . To handle this problem it is now designed the system safety valve on 100m2 has a safety valve , this valve system works completely eliminate buoyancy force .

 

2 . Tiling pool

 

For years we often use glass tiles for tiling the pool . However, Vietnam still does not have tiles for use in swimming pools so still have to use the tiles for the kitchen , bathroom. The downside of this type of tile is very fast peeling , cracking place despite gel was dedicated . Currently the world pool tiling technology mainly used two main types :

- Specialty glass tiles : Pool size 10.5cm x 10.5cm ; 15cm x 15cm tiles vessels 2.5 mm - 3 mm . Because of small tiles but large brick circuit so difficult flaking almost cracked . advantage of the rich diversity of colors , can be decorated into vivid pictures . The downside is usually moss clinging to the brick so the circuits do sanitation relatively time consuming .

- Covering the bottom of the tank and PVC Polyester : Made from Polyester PVC used for finishing the inside surface of the tank . The advantage of this type of PVC sheets are absolutely waterproof , when punctured , torn countries still need to remove the bullet and is , shorter construction time than tiling with glass tiles , eliminate additives waterproofing of concrete unnecessary . Even when pitted concrete , cracked to 15mm and do not water loss , not affecting the use of an exploit . Often times the use of this type of sheets from 20-25 years . Another feature that can be decorated by printing on different types of decorative sheets . In the world today , there are many kinds of quality sheets but there are relatively large differences due to the different characteristics of each product . One can select products suitable for the conditions in Vietnam which is kind of Polyester PVC sheets - Flagpool of Italy. Type mats are manufactured using the most advanced technology of the world today : anti- tear fiber mesh layer and is handled completely non-toxic , anti- sonar external adverse impact on the human brain used when diving in the pool , have UV protective coating and UV protection against aging under the sun is very suitable for the climatic conditions in the harsh summer sun Vietnam . Price of this product is reasonable about 489,000 VND/m2 perfect , especially for color plus 10-20 % in price . This product is genuine warranty and 10 year period of use is 20-25 years . With the family pool , pool or pool business can put children in such a vivid picture of the truth. Paintings , prints at the bottom of the tank or to order about 1.800.000d - 2.000.000d/m2 . Polyester PVC pads - Flag pool currently used for most of the pools in the world thanks to the advantages mentioned above . In Hanoi , more than 20 new public swimming pool construction from 2000 to present , up to 16 tanks using PVC Polyester Lining - Flag pool . And the family pool almost 90% of the material used .

 

V. filtration system and water treatment of swimming pool

 

1 . The concept of water purification systems

 

Because the water in swimming pools daily inspiration to dust from flying apart into , angry hate swimming emitted by the water very quickly so dull . Furthermore, the organic matter excreted by humans during swimming is very good conditions for algae , bacteria growth . The filtration and water treatment to retain residue and algae . Since ancient times , people have to use sand to filter river water , lake before going into use .

Department of Sport Hai Duong is an example : Until August 2004 it still uses this method to club swimming pool diving Kieu . It is built of sand and 3 tank effluent pump water from the city of sand that filtered through 3 tanks before being used tank . After a few days of cloudy water they do use alum bottom sediment type and smoking outside. In fact this method is very dangerous for the skin , the eyes and childhood intestinal disease , such as if playing drinking . But with her ​​distant city or poor rural areas , still have daily swimming in rivers and ponds of stagnant water , the method is also somewhat reduce accidents ( This is also flaunt achievements . Numerous public projects worth hundreds of billion they sought recourse capital , is built of . , but a few hundred million filters to protect the health of the child " generation of our future " , the year and there are dozens who cares ) . Equipment types of water purifiers available : Membrane Filter cloth , filter core fiber , paper and centrifugal filtration method but common and easy to use sand filter is still the best . In addition to its ability to better filter has the ability to cause the precipitation of impurities . When the smaller particle suspensions 30mμ crept through deep sand floor creates friction charged , when they themselves suck out the tank tightly together to form larger particles and sand filter next time will be blocked .

Attached to the filtration system is the system automatically adjusts the pH and chlorine levels in the water . The downside of this system is to use very pure chemicals . If no rule is only a few months , fire pumps while pure chemicals 10 times more expensive than common chemicals . Economic conditions our country can hardly be used for mass . So many units after installation of this equipment does not dare to use because if you use this system is only a few months left to go is a waste . However can be overcome by : chemicals in container prior to use mixer beat thoroughly , and used to melt stainless steel mesh filter carefully .

 

2 . Principles of design water purification systems

 

A basic principle to keep in mind when designing the agricultural water pushed in from the beginning and started smoking from deep and is arranged so that maximum advantage filtering capacity . Many tank top on and push the nozzle too close to the water after it is filtered and put into tanks of purification was turned on while the filter dirty water pools that sit in the corner just vicious in the tank. Sand Filter has two types: high quality and 30m3/h/m2 50m3/h/m2 common type ( the same volume of water through the filtration area as big as efficiently filter ) . Most pool Vietnam are kinds 50m3/h/m2 used for device costs only 0.75% of the price of high quality filtration equipment 30m3/h/m2 .

 

2.1 . Calculation capacity water purification equipment

Requirements of filters is from 4 to 6 hours in an entire country should be run through the filter 1 time . Time running water in the tank through the filter shorter the possibility of water damage occurs less dramatically and the cost of water treatment chemicals as low . The calculation of the capacity for appropriate filtering devices rely on a number of basic principles :

- Large surface area - outdoor pool - pool very crowded business of substandard water as much lime scale , metal ... 4h/lan time not exceeding 0.4 even shallow pools - 0.6 m and where many wind dust filter should 2h/lan time .

- Swimming in the house - at the pool - good water - chemicals used full time can filter up to 8h/lan .

2.2 . The formula filters

1 - Determine the volume of water filtration needs .

2 - Select the type of refinery has a capacity accordingly.

3 - Determination of circulating filtration time .

4 - Determine the number of filters required using the formula

= Number of machine tank : Hours circulation filter : Refinery Capacity

For example :

A pool of 25m x 50m x 2m = 2.500m3 water

Select the type of filter 125m3 / h filtration time 4h/lan

2.500m3 : 4h = 625m3 / h : 125m3/h/may = 5 refinery 125m3 / h

Use a filter 60m3 / h filtration time 8h/lan

2.500m3 : 8h : 60m3 / h = 7may filter 60m3 / h .

Note: For public swimming pools to choose suitable refinery capacity and minimal use of two or more machines , the first machine malfunction can still work temporarily while awaiting repairs .
